Enzymes are biological (a) produced by living cells.
Enzymes reduce the amount of (a) energy required to start a chemical reaction.
Enzymes consist of (a) protein with a specific tertiary structure.
The active site allows only specific (a) molecules to enter and binds via non-covalent bonds.
The induced fit hypothesis stated that the active site is (a) .
Increasing the temperature increases the chances of (a) between enzyme and substrate.
Above optimum temperatures cause the breakdown of (a) and hydrogen bonds that hold the tertiary structure of enzyme molecules.
In a (a) inhibition, the enzyme reaction slows down as end products accumulate.
(a) is a class of enzymes that catalyses the rearrangement of atoms within a molecule converting one isomer to another.
(a) modifies the chemical structure of enzyme that enable the enzyme to function more effectively.
The rate of reaction doubles for every 10 degree celcius rise in temperature.
True
False
The lower the Km value, the lower the enzyme affinitiy for its substrate.
True
False
Competitive inhibitors compete with the substrate for the same allosteric site.
True
False
Noncompetitive inhibiton can be overcome by increasing the substrate concentration.
True
False
In cooperativity, binding of an activator to active site of one subunit stabilizes the active form of other subunits of enzymes.
True
False
Immobilised enzyme can be easily removed from the reaction and can be reused.
True
False

True
False
Attachment of enzyme onto a support material via ionic interaction is a covalent bonding method in enzyme technology.
True
False
In entrapment method, enzymes are trapped within a confined space.
